David Black, the head of water regulator Ofwat, is set to resign. This follows the government's announcement of plans to abolish Ofwat and establish a new water watchdog. The move signals a significant shift in the regulatory landscape for the water industry, prompting questions about the future direction and oversight of water companies and their environmental and financial performance. The details surrounding the transition and the specific mandate of the new watchdog remain to be seen, but the change aims to improve accountability and effectiveness in the sector.
